The original house had been extensively renovated by the previous owners and was already featureworthy, but the sun-drenched rooftop addition makes guests feel like they're leaving the city behind. Air and light sweep into the space, as a wall of floor-to-ceiling operable windows blurs the line between inside and outside.On warm days, the couple opens up the rooftop space to the surrounding views and relaxes on the outdoor sectional, made by Toronto's Andrew Richard Designs. The inventive coffee table lends an industrial touch and intriguing texture to the space. John, who also holds an architecture degree, designed and built the low table as an anniversary present for Wanda. It's made up of multiple pieces of plywood clamped together with threaded rods and castors.
